Impact of immediate general anesthesia in the emergency room on prevention of rebleeding after subarachnoid hemorrhage.

Background: Aneurysm rebleeding is fatal in patients with aneurysmal subarachnoid hemorrhage (aSAH). We aimed to investigate whether immediate general anesthesia (iGA) management in the emergency room, upon arrival, prevents rebleeding after admission and reduces mortality following aSAH.

Methods: The clinical data of 3033 patients with World Federation of Neurosurgical Societies (WFNS) grade 1, 2, or 3 aSAH from the Nagasaki SAH Registry Study between 2001 and 2018 were retrospectively analyzed.

Characteristics of aneurysmal subarachnoid hemorrhage associated with rheumatic disease.

Spontaneous subarachnoid hemorrhage (SAH) occurs due to intracranial aneurysm rupture in most cases. Rheumatic disease may cause vessel wall inflammation, which can increase the risk of rupture. However, the characteristics of SAH with rheumatic disease are unknown.

Impact of perioperative aneurysm rebleeding after subarachnoid hemorrhage.

Objective: Aneurysm rebleeding is a major cause of death and morbidity in patients with aneurysmal subarachnoid hemorrhage (SAH). Recognizing the predictors of rebleeding might help to identify patients who will benefit from acute management. This study was performed to investigate the predictors of aneurysm rebleeding and their impact on clinical outcomes in the preoperative, intraoperative, and postoperative periods.

[A Case of Metastatic Brain Tumor Complicated by Multiple Repeated Hemorrhages].

Metastatic brain tumor occasionally results in multiple cerebral hemorrhages. Here, we report a case of metastatic brain tumor complicated by multiple repeated cerebral hemorrhages. An 80-year-old man with a history of removal of lung cancer was admitted to our hospital because of disturbed consciousness following headache.

[A Ruptured Aneurysm at the Origin of a Duplicated Middle Cerebral Artery, Treated by Coil Embolization:A Case Report].

Duplication of the middle cerebral artery(MCA)is an anatomical variant of the MCA, originating from the distal portion of the internal carotid artery(ICA)and supplying blood flow to the tip of the temporal lobe. Cerebral aneurysms rarely develop at the bifurcation of the ICA and the duplicated MCA, but when they do develop, they may result in subarachnoid hemorrhage. We treated a 41-year-old man, who was urgently brought to our hospital because of severe headache.
